I used all three too. Some had helpful information that the others did not. But I feel like Jacaranda and Contexts sometimes give too much detail.
There's a bit in Conquering Chemistry (Module 3) about how, when naming straight chain haloalkanes with more than one halogen, you have to take into account the electronegativity of the halogens - which is no longer valid (according to the Royal Australian Chemical Institute). Instead, you're meant to take the lowest set of locants.
